Two main frontal areas have been implicated in the dream process. The first involves the deep white matter of the frontal lobes (just above the eyes). The main systems at work here involve the mesolimbic and mesocortical dopaminergic pathways. There are connecting fibres that run between frontal and limbic structures.
Studies have found that as little as 36 hours of sleep deprivation can cause a performance reduction in tasks requiring these executive functions. [27] Frontal lobe. The processes above illustrate a model of controlled versus automatic behavior that was hypothesized by Shallice et al. (1989), called the supervisory attentional system.
Sleep deprivation studies show that sleep is particularly important to normal brain function. Sleep is needed to remove reactive oxygen species caused by oxidative stress (and generally autophagy) and to repair DNA. REM sleep also decrease concentration of noradrenaline, which when in excess amount causes the cell to undergo apoptosis.
Note that there is no "central lobe"; due to their placement, and depending on the individual, the "C" electrodes can exhibit/represent EEG activity more typical of frontal, temporal, and some parietal-occipital activity, and are always utilized in polysomnography sleep studies for the purpose of determining stages of sleep.
The differences in neuronal activity of the brainstem during waking and REM sleep were observed, and the hypothesis proposes that dreams result from brain activation during REM sleep. [1] Since then, the hypothesis has undergone an evolution as technology and experimental equipment has become more precise.
In the field of psychology, the subfield of oneirology (/ ɒ n ɪ ˈ r ɒ l ə dʒ i /; from Ancient Greek ὄνειρον (oneiron) 'dream' and -λογία 'the study of') is the scientific study of dreams. Research seeks correlations between dreaming and knowledge about the functions of the brain, as well as an understanding of how the brain ...
“Sleep is where all of our recovery happens, and it’s got to be in a row, and it only happens when you get a certain kind of sleep,” says Dr. Pristas. “You can’t divide your sleep up and ...
It was found that upon awakening the visual area, frontal cortex, limbic lobe were activated (in the intense activation phase) and the frontal cortex, temporal cortex, primary motor area, and insula were activated (in the post abrupt awakening phase). Therefore, the study concluded that decision-making was not activated immediately upon waking ...
